EXPLOSIVE-ENGINE.

Specification of Letters Patent.

Patented 'May 12, 191

Application filed February 25, 1913. Serial No, 750,657.

To all whom 'it may concern Be it known that I, SAMUEL I'Inxnr Dann, a citizen of the United States.y and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in `llxplosive" Engines, of which the followingis a specitication.

My invention relates to improvements in explosive engines and especially to the means for supplying the fuel thereto, the object of the invention being to provide improved means for supplying fuel, whereby the starting and running of the engine is facilitated.

rIhe invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawingforming a part of this specification, and in which- Figure 1 is a view illustrating my invention and shown in position of use in conjunction with the ordinary exhaust pipe and the ordinary intake pipe or manifold of the engine, Fig. Q, a face view of a valve chainber employed in the construction, Fig'. 3, a section taken on line m-m 0f Fig'. 1, and Fig. 1, a detail perspective view of a valve employed in the construction.

The preferred form of construction as illustrated in the drawing, comprises a valve chamber 1 which is passed through the or dnary dash board 2 of` an automobile and secured thereto by means of a suitable securingflange Valve chamber' 1 is pro vided with a valve 4L as shown in detail in Fig. 1, said valve being operated by means of a valve stem 5 carrying an operating' handle 6 which is arranged in operative relation with a dial 7 on chamber 1 and located immediately behind dash board 2 so as to be in position for convenient access by the driver of the car. A pipe 8 is arranged with one end 9 in close proximity to the top of the ordinary exhaust pipe 10 of the ordinary engine, (not shown). This pipe 8 leads through a supplemental carburetinp; chamber 11 and is provided with an opening- 12 in said chamber, said chamber being partially filled with wicking,` or other suitable absorbent material and being supplied with gasolene or other suitable fuel'. At its other end 13 pipe 8 is connected with valve chamber 1 and another pipe 14; leads from val ve chamber 1 into intake pipe or manifold 15 as indicated. The end of pipe 111 projectinginto pipe 15 is provided with a suitable strainer 1(3which extends well into pipe 15 and serves to strain any fuel passing),- therethrough and also to facilitate evaporation thereof and thorough mixing' with the air in pipe 15. Valve chamber 1 is also provided with an oil cup 17 leading thereto and which may be of any usual or desired construction.

In operation heated air is drawn through pipe S and valve chamber 1 into thc intake pipe 15 by the action of the ordinary suction of the engine as will be readily understood by those skilled in the art, said air absorbing'4 a certain amount of gasolene or other fuel from chamber 11 thus tending' to enrich the mixture and facilitate starting and running' of the engine. Under ordi nary conditions gasolene or other fuel is earried in oil cup 17 and permitted to run down into casing- 1 where it seeps around valve 4t,`

which [its sufficiently loose in casing' 2 to permit such passage of the 7gfasolene or other fuel `under the iniuence of the engines suetion already mentioned to facilitate carbureting the air drawn through pipe 111.

Then it is desired to remove the carbon from the engine a mixture of turpentine and kerosene is supplied to the oil cup 17 and this mixture will thus be introduced into the engine and provide its usual function in the removal of the carbon therefrom.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with the exhaust and intake manifolds of an explosive engine, of a pipe having one end adjacent said exhaust` nniniifold and its other end connected with said intake manifold; a primary fuel supply recordado pierced by and in communication with said pipe; a valve casing connected in said pipe; an auxiliary fuel supply receptacle connected with said valve casing; and :i valve in said valve casing controlling the passage through said pipe and permitting fuel to pass between said valve and its casing into said pipe, substantially as described.

2. The combination With the exhaust and intake manifolds of an explosive engine, of a pipe having one end adjacent said exhaust manifold and its other end connected With lsaid intake manifold; a fuel supply receptacle pierced by and in communication With said pipe; a valve casingconnected in said pipe; a cleansing' material receptacle connected with said valve casing; and aV valve in said valve casing controlling the passage i name to this specification in the presence of 20 two subscribing Witnesses.
